TNZ whom it may concern:

Be it known that I, FREDRICH J. Room, a citizen of the United States,residin at Chicago, in the county of Cook and tate 6 of Illinois, haveinvented certain new and useful Im rovements in Ex anders for Metal Bare Heads, of which t e following is. a specification. t

This invention relates to expanders for metal barrel heads, and one ofthe objects of the invention is to provide an improved device of thischaracter by means of the use of which metal-barrel heads may beefliciently and expeditiously expanded 'for securing them in position onbarrels, and in a single operation.

A further object is'to provide an improved portable hand device adaptedto,be I actuated by fluidpressure. A further object is to provide animproved device of this character which will be of asimple'andcomparatively light con:

struction and eflective and eflicient in opera tion. 26.

jects as will appear, the invention consists in the features of noveltyin substantially the construction, combination, and arrange- 'ment ofthe several parts hereinafter more fully described and claimed and shownin the accompanying drawings illustrating this invention and in which;

Figure 1 is a view partly in elevation, partly in section and partlybroken away of a device of this character constructed in accordance withthe principles of this invention. Figure2 is an enlarged detailsectional view of the controlling valve and ports.

Figure'3 is a view partly in elevation and partly in section of aportion of the expand er showing the parts in a different position thanthe position they occupy in Figurel. Figure 4 is a sectional view takenon line 44 Figure -1 and Figure 3.

Referring more particularly to the drawings the numeral 10 designates acylinder of any desired size and configuration and within which cylindera piston 11 is reciprocable.

Connectedwith the piston 11 is a piston rod ,12 which extends throughone end of the cylinder to project therebeyond and a To theattainment ofthese ends and the accomplishment of other new and useful obsuitablepacking 13 is provided to form a fluid tight joint between the pistonrod and the end of the cylinder.

Connected with the cylinder and disposed I therebelow is a suitablesupport 14, and the cylinder is Isu ported thereby in any desired orsuita le manner, referably by means of upright bars or rods 15; suitablyconnected with the respective parts. 7

Arranged below the support 14 so as to slide thereagainst, are aplurality of expander members 16, any number of which may be provided,preferably four and they are preferably of a segmental configuration.

Individual to "'and connected with the members 16 are ears or uprights17 which extend through suitable slots 18 in the support 14, the slotsbeing ofsuch a length that the reciprocation or move ent of the members16 with respect to the support 14 will not be interfered with. Theseears. project beyond the support 14 and are provided with flanges 17*which engage and are movable upon the face of the support 14 and serveto assist in maintaining the members 16 against displacement withrespect to the said support.

Link members 19 are pivotally connected by one end as. at 20respectively with the ears or projection 17. These links may be of anydesired length and are also res ectively pivotallv connected as at 21,wit a collar 22, which collar is connected with the piston rod 12 forreciprocation therewith. With this construction it will be manifest thatwhen the piston rod 12 is reciprocated; carrying with it the collar 22,theexpander members v16 will be moved with respect to the support14-and'toward and away from each other in directions transverse to thedi- 10 preferably through one end thereof and on one side of the piston11, is a fluid conductor pipe22. Communicating w1th the cylinder 10 ontheopposite side of the piston 11, such as by means of a passage 23 inthe end 'of the cylinder; is a fluid conductor pipe 24. These pipes 22and 24 have communication with a valve casing 251 the can ing itselfhaving an opening 26 which has -The valve casing is also provided with aport or passage 27 with which the pipe 22 has communication, and thevalve casing is" also provided with a port 28 with which the pipe 24 hascommunication, there being also provided an exhaust port 29 in the valvecasing 25; i

A valve is rotatable in the valve casing and is provided with passages31, 32 which are adapted, when the valve is properly ro-. tated, toestablish communication from the supply opening 26 with the openings 27,28 to the cylinder on opposite sides of the piston. The valve 30 is alsoadapted through the ports 31 and 32', to connect the passages 27, 28respectively with the supply opening 26 or the exhaust opening-29. Thepassages in the valve casing 25 and in the valve 30 are so arranged thatproper connection may be established between the openings 27 and 28 andthe exhaust open- 'Anysultable means may be provided for actuating thevalve 30. To that end a handie 33 which is connected with the cylinder10 for transporting the latter, may be used for that purpose. The handle33 is rotatably mounted with respect to the cylinder 10. A

.stem 34 is connected with the valve'30 and is also connected-with thehandle 33 for rotation therewith, with the result that when the handle33 is rotated about its axi with respect to the cylinder 10, the valve30 will be correspondingly rotated.

In use, a metal end 35 is placed upon the barrel end 36, the end 35being preferably providedwith a flange 37 engaging over the edge of thebarrel for supporting the end.

After the end has been placed in position on the barrel, the expander isplaced in position so that the members 16 will contact with the face ofthe end 35. The valve 30 is then positioned so as to admit fluid intothe cylinder 10 above the piston 11, and to connect the opening 23 inthe end oii the cylinder on the opposite side of the-piston with theexhaust opening 29. Fluid then entering the cylinder on the upper sideof the piston will force the piston downwardly or toward the oppositeend of the cylinder. This will lower the collar 22 and through the medumof the links 19,, the expander members 16 will be moved so that theperipheral edges 38 of the members 16 will 'force a portion of the metal35 into the chine 39 of the barrel, thereby expanding a portion of theend and. securing the end to the barrel, as

shown in Figure 3.

. The handle 33 is then rotated to position the valve 30 so thatconnection will be established between the lower end of the cylinder 10through the port or passage 28 and the The pressure on the lower face ofthe piston will cause the piston to rise in the cylinder 10, and thiswill retract the expander members 16 from the position shown in Figure 3to the position shown in Figure 1.

When the barrel is arranged uprightly it will be manifest that theexpanding tool may be placed in position upon the end 35 to be supportedthereby. I

With this improved construction it will be manifest that there isprovded a simple and efficient device for quickly and eflicientlyexpanding a metal end and securing the same in position.

- It will also be manifest that there is provided a compact device whichwill be easy to manipulate and which will be easy to handle.

has been herein shown and described, it is to be understood that variouschanges may be made in the details of construction and in thecombination and arrangement of the several parts, within the scope ofthe claims without departing from the spirit of this invention. a
